Ok that explains my problems here too I guess. I wrote some months back,
that i get transferrates of 3-4k with filiago. That problem is at least
reproducible by others ( I have 2 people that have that problem too,
all technotrend premium cards) Video works fine here (I use it for
every day use) but IPviaSky is a no go. I had the hope i could do some
tests with a skystar2, but the test device i have here is a skystar 2
rev 2.6b . So I wonder at the moment if there are people that can use
IPviaSky under Linux at all. I was told to get in contact with tellique
people for this issue, but that isnt easy either. At least linux-dvb
,ailinglist is very interesting for me the last days. ;)
